GRAENQMEASURNG iViACHiNE.

SPECIFICATION forming part of 'Letters Patent No. 392,452, dated November 6, 1388.

Application filed April 17, lSSS.

To all whom it may concern.-

Be it known that l, BEAUMONT PARKER, a citizen of the United States of America, residing at Highlands, in the county of Donophan and State of Kansas, have invented certain new and useful Improvements in Grain- Measuriug Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

rlhis invention pertains to certain new and useful improvements in grain-measures, having for its objectl the provision of simple and highly efficient means for measuring grain as the same is emitted from a thrashing-machine and emptying the same automatically after the desired quantity has been secured.

The invention comprises the detail construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a central vertical sectional view of my improved grain-measure, and Fig. 2 is a horizontal sectional view thereof.

Referring to the drawings, designates the box or inclosing-casing,in the upper and lower portions of which are formed openings a u', through which the grain is respectively received and discharged.

B is the measuring can or vessel, divided into two equal-sized compartments, b b, having inclined bottoms b2 extending from the central partition-board, if, to the outer ends of the can or vessel. The top of the measure is open, and the sides are preferably curved at their upper ends.

O is an approximately U shaped lever-frame fulcrumed near the forward ends of its side arms to the inside of the box or easing A,as at d, and between the outer ends of these side arms is pivotally secured the can or vessel B, the same being held by a cross-rod, d', passed through an aperture in the partition b3. From the rear connectingbar of this lever-frame O projects an arm, D, whereon is adjustably secured a weight, E.

The can or vessel B is provided with two end-gates, F F', pivotally secured at their upper ends, so as to permit their lower ends to swing outwardly. These end-gates are con Serial No. 270,910. (No model.)

nected at their side edges by connecting-rods fj", from the centers of which project small rollers f2 f2, designed to play in vertical slots f3 in the sides ofthe box or casing, one of said 55 slot-s being shown in Fig. l.

To the upper central portion of one side of the can or vessel B is secured a stud or pin of a small roller, g, designed to come in Contact with and to be held by hooks G G,attached to 6o the inner side of one ofthe sides ofthe box or easing A, said hooks being pivotally secured at their outer ends and held as against too great downward movement by means of pins y .0-

In practice the can or vessel B always maintains an inclined position, it being so held by the roller g' and one ofthe hooks G G.

The operation is as follows: Supposing the can or vessel to be in the position shown, grain, 7o on being admitted through the opening ,will fall into the compartment Z), the end-gate of which is closed, as shown. Upon the compartment being iilled with grain the weight thereof will cause the lowering of the can or 7g vessel as against the action ofthe weight, the disengagement ofthe roller g from the hook G, and the movement of said can or vessel on its pivotal cross-rod. This movement ofthe can or vessel will, throughthe agency of the connecting-rods f f,eause the opening of the endgate Fl and the closing of the end-gate F, thus permitting the grain to pass from the partition b out through the lower opeiiing,a,into the bag c r other receptacle placed thereat. 85 Vhile this is being dene the grain is passing into the other compartment, b, of the can or vessel, which is held in position by the hook G and roller g. Vhen the desired quantity of grain has been secured in the compartment b the weight thereof, causing the depression, will effeetthe lowering of the can or vessel and the disengagement of the roller g from the hook G', immediately upon which the end gateF will be opened and the other end-gate closed, so that the compartment b will again be ready for reception of grain.

The parts are so constructed and arranged that sufficient grain will be passed from one compartment and sufficient received in the other compartment to prevent the roller g moving beyond the inner hooked end of each hook G G, so that the emptying ofthe grain in the compartment just filled will cause the can or vessel to move upwardly, and said roller Will come in contact with the shoulder of the adjoining hook.

From the foregoing; description it will be seen that by means of the Weighted lever-frame the can or vessel is normally held elevated, and that upon filling of one ofthe compartments of said can or vessel the latter will be lowered as against the Weight E, and the roller g being freed of thelhook, said can or vessel will turn on its pivotal bearing, causing the opening of its end-gate and the discharge of grain therefrom. The can or vessel will then rise to its normal position, causing the roller f/ to come into engagement with the other hook.

By means of my invention grain is easily, readily, and accurately measured, a'nd the device is extremely simple, cheap, and durable, and embodies advantages in points of siniplieity, durability, and general efficiency.

'I claim as my inventionl. The combination, with the box or inclosing-casing having slots in its side Walls, of the Witnesses Gnonon WiNrnRs, WnsLnY TREVETT.
